Boy did I suffer in Japan for 2 years. I hated tea, fish, vegtables, rice, noodles, and about everything Japanese ate. It was expensive, but I survived by going to American style hotels that served American style dishes. I also found a small resturant near my apartment that the cook was willing to TRY to cook down home style. When I was broke, I could always go back to the military base where I worked to eat. I will say I left Japan pretty skinny, but a chance to see Japan is worth any suffering you might endure. Good luck and enjoy!
